EPS controller will determine the appropriate assist level. This system is compact but very expensive;
any failure of the motor, sensor or internal mechanical devices makes the steering gear replacement
necessary.
The double pinion EPS
system has the motor
assembly located in a
separate housing. The pinion
motor drives a second pinion
gear to assist the pinion
attached at the column. The
system is not as complex as
the Acura one but is larger and requires more space under the hood. The EPS motor can be serviced
separately.
The Honda Insight, Civic Si and Hybrid along with the Toyota Prius use an EPS system which has the
electric assist motor
mounted to the steering
gear’s pinion assembly. The
electric motor is directly
linked to the pinion gear and
is serviceable. This system
is compact and cost
effective. It will take up
slightly more room than a
conventional rack and
pinion steering gear.
The column mounted EPS system has the motor
assembly mounted to the column. The motor
will assist the driver’s steering input through a
worm shaft and reduction gear. This system uses
a very compact rack and pinion assembly, the
motor occupying the open space under the
instrument panel cluster.
